Abstract (en)
Thermal printer mechanism comprises a frame (7) comprising on each side a flat profile portion (8), a thermal printhead integral and fixed to the frame (7) (3) with a thermal dot line (10), a platen roller (4) having a gear (6) at one end of its axle (12) that is able for tangent contact with and to move in translation along the flat profile portion (8), in order to be guided and aligned to the thermal printhead (3) dot line (10), pressure means (11) to urge the platen roller (4) against the printhead, a motor (21) to move in rotation the platen roller (4), a helicoid screw (9) for transmitting of the mechanical power from the motor (21) to the platen roller gear (6), said helicoid screw (9) being positioned substantially perpendicular to the printhead (3) and engaged into the platen roller gear (6) when the platen roller axle is in tangent contact with the flat profile portion (8) of the frame.
